DDR1 protein expression is induced in white adipose tissue and liver after 12 weeks on HFD. (A-E) DDR1 expression was assessed by immunoblot in epididymal adipose (A; eFat), subcutaneous adipose (B; sFat), interscapular brown adipose (C; BAT), liver (D), and muscle (E) tissues isolated from Ddr1+/+ mice after 12 weeks on CF or HFD (n = 6). Immunoblots were quantified and normalized to β-actin and expressed as integrated density values (IDV). Statistical analysis was performed by two-tailed student's t-test. The values are mean ± SEM. ∗p < 0.05, ∗∗p0.01.
